Fifty years ago, when I was a young trooper with a steady hand, I did some exhibition shooting. I used a first generation Colt Trooper loaded thusly. .38 Special brass, with the flash hole drilled out, leaving more than enough shoulder to hold the primer. Push the unprimed case into a block of paraffin, Gulf Wax, available at grocery stores, if my memory is still good. This loads the projectile -think cookie cutter. Insert primer. No powder needed. You can target shoot with this. An aiming point above the target is required, as there is no recoil to speak of. A bullet trap of some kind is required. I used a box filled with magazines. It will penetrate drywall at 30-40 feet! Mark your case heads so that you don't mix them with the real stuff. Back then I filled the head stamp markings with red nail polish. There are more and better permanent markers available today.
I see no reason this would not work in straight wall chambered rifle. A top break single shot (TC Contender et al) might be ideal. The rifles might not tend to shoot so low.
I do not recall how often cleaning was required. I started the demonstration with a clean, lightly oiled bore. Most demonstrations involved less than fifteen rounds and the bore and chamber was cleaned immediately for duty ammunition.
I try to keep a good supply of .22 lr on hand. I don't think I dropped below 7000 rounds and I did not buy any from black marketers during the latest crunch. Pellet guns are a good alternative for I targets and plinking.
Not a writer, butI thought this might interest some.
